The Chief of Staff glossary
The working vocabulary of the role, defined plainly. If a term you need is missing, it probably belongs here — join the list below and tell us.
- Action item
- A discrete commitment produced by a meeting or decision, with a named owner and a due date. Tracking action items to completion is a core Chief of Staff responsibility.
- Air traffic control
- Shorthand for the coordination function a Chief of Staff performs: sequencing initiatives, deconflicting priorities across teams, and protecting the principal's time.
- Business review
- A recurring meeting, usually monthly or quarterly, where owners present performance against agreed metrics, explain variances, and commit to corrective actions.
- Chief of Staff (CoS)
- A senior role that extends an executive's capacity by running the operating cadence, driving cross-functional projects, and ensuring decisions are made and executed. The CoS borrows the principal's authority rather than holding line authority.
- Daily brief
- A short morning summary for an executive covering what changed, what needs attention today, and what is at risk. Increasingly generated with AI from captured notes and communications.
- Decision memo
- A short written document, typically one to two pages, that frames a single decision: context, the question, options with trade-offs, a recommendation, and execution steps.
- Executive Assistant (EA)
- A role that owns an executive's logistics: calendar, travel, expenses, and meeting mechanics. Distinct from a Chief of Staff, who owns substance and follow-through.
- Follow-up list
- The consolidated list of commitments, delegated items, and deferred topics a Chief of Staff maintains so nothing the principal hands off is dropped.
- Force multiplier
- A common description of the Chief of Staff role: someone whose work increases the output of the executive and leadership team beyond what any of them could achieve alone.
- GEO (Generative Engine Optimization)
- The practice of structuring content so AI answer engines can find, understand, and cite it, analogous to SEO for traditional search. Relevant to any team publishing authoritative content.
- Offsite
- A dedicated multi-hour or multi-day leadership session, held away from routine work, for strategy, planning, or team alignment. Typically designed and produced by the Chief of Staff.
- One-way door decision
- A decision that is difficult or impossible to reverse, warranting slower deliberation and senior attention. Contrasted with two-way door decisions, which are reversible and should be made quickly at lower levels.
- Open question
- An unresolved issue that blocks or shapes a decision, tracked explicitly so it is either answered or consciously deferred rather than forgotten.
- Operating cadence
- The recurring rhythm of meetings, reviews, and planning cycles through which a leadership team runs the business: weekly leadership meetings, monthly business reviews, and quarterly planning.
- Pre-read
- A written document circulated before a meeting containing the status, context, and proposals attendees need, so meeting time is spent on discussion and decisions rather than presentation.
- Principal
- The executive a Chief of Staff serves, most often a CEO, president, or division head. The CoS role is defined relative to the principal's needs and delegation.
- Shadow organization
- A failure mode in which a Chief of Staff becomes an unofficial gatekeeper who filters all access to the principal, breeding resentment. Healthy CoS practice keeps direct lines between the principal and their team open.
- Special project
- A time-bound, cross-functional initiative with no natural single owner that the Chief of Staff drives on the principal's behalf, such as a pricing change, market entry, or reorganization.
- Stakeholder map
- A working inventory of the people who influence or are affected by an initiative, with notes on their positions and concerns. Used by a CoS to sequence conversations and build alignment before decisions.
- Synthesis
- The core Chief of Staff skill of compressing large volumes of discussion, data, and documents into the short, accurate summaries executives act on.
